While most services catering to the whims and fancies of humans have either already been fully exploited or are lacking the technology to make them possible (Transporter! Transporter! I want an f-ing Transporter!), think of all the products that have yet to be created for animals! Think of how much more you can buy!
While the market for pet accesories was largely created when Paris Hilton started brandishing about her Chihuahua, Tinkerbell, as an accesory (ironic and tacky) it has since expanded to necesitate, not just fashion shows, but an entire fashion week. "And in perfect time for the buying season".
Now before you say to yourself, "pet and fashion... an entire tradeshow... that seems silly", please, remind yourself that:
a) You don't live in New York, of course it doesn't make sense, your animals are probably more like, oh, say, animals, than the inglorious children they serve to be here in the City (and parts of Connecticut).
b) The website for PFW is actually pretty well laid out, with an awesome line drawing of a barking wolf humping a weiner dog done by Graphic Designer/DJ Jason Tranchida. Pet Fashion Week, starting to justify itself...
c) Rich people need to be given a venue in which they can spend money to feed artist's drug and food habits. Otherwise, what would they spend their money on? Probably just their children. And that would truly be a waste.
